Locomotive Turbo boost?

[trc46]

So I saw a train turbo today and the guy said it was 200k. How much boost does one make?

I can't remember but as a senior trip for our industrial arts class, our teacher took us to a place where they manufacture and test turbos for trains. The test nodule was something like twenty feet down in a concrete hole. Walls were four feet thick. They would spool the turbos to something like 200% of duty cycle and see if they held up. Tour guide mentioned it was pretty damn impressive when one failed. Sent the turbines pretty deep into the concrete.

I've seen steam turbine's shed bladed before.. it's NOT a pretty site, and the turbine casing doesn't do anything to stop them.. I'd imagine a turbo supercharger is pretty much the same thing..

Locomotive diesels are 2 strokes. So boost numbers probably are not that high but the cfms are insane.

I could be horribly wrong here.

Me too. Not a pretty sight at all. Don't want to be near it.

Over speed trip test used to scare the crap out of me. lol

EMD's are two strokes.all the new GE diesels are 4 stroke:banana:

Bam! Knew I wasn't completely right.:beer:

Reading around the internet from people who operate them it seems 40-50psi at around 18k rpms with a inlet of 1000-1300 CFM wasn't uncommon. They also go for around $75k new.

You so smart.

You so smart.

Are you another

?

Locomotive technology is pretty cool stuff. Nothing like the sound of 3 new GE loco's going through a tunnel in full pull. Can be catastrophic when a failure happens CN Locomotive 2699 - Yellow Bullet Forums

Oh you don't seem to grasp sarcasm, I retract my previous statement.

I don't think you have any fans...

GE's have been 4 strokes since the early 60's for their own in house prime mover, the FDL-16. This started out with the U25B. But, EMD>GE all day every day!

Plz post link, cause most locomotives have an engine disable function called overspeed that shuts the engine down if it goes above 900rpms

FYI, most Turbos on locomotives are there for cooling the engine not for HP

Pretty sure 18k rpm was the blower speed, not engine speed.

GE>EMD,, imo emd is way behind the GE's in comfort, power, and operator controls.

 

[White608]

All the large diesel engines I've seen run no more than 3000 rpms. Usually the bigger they are the slower they go a 3616 runs 1,000 rpms


I've read that some of the turbo ADRL cars are around 60psi ....

How does it work for cooling ? I've never seen them used for that, I've seen them used to help emissions.

The new ge tier 4 prime mover is a v12 runs at 950 rpm in 8th notch. Turbo speed is around 23k. But nothing in the display screens show boost psi. Im a locomotive electrician and ive been trying to find the boost psi too.
